Magazi amazungulira thupi lonse, kupereka zakudya kulikonse ndikuchotsa zinyalala, kotero ayenera kusungidwa bwino nthawi zonse. Komabe, pamene mtsempha wamagazi wavulala ndikusweka, thupi limapanga zinthu zosiyanasiyana, kuphatikizapo vasoconstriction kuti lichepetse kutaya magazi, kusonkhana kwa ma platelet kuti aletse bala kuti lisiye kutuluka magazi, komanso kuyambitsa zinthu zotsekeka kuti apange thrombus yokhazikika kuti ilepheretse kutuluka kwa magazi ndi Cholinga chokonzanso mitsempha yamagazi ndi njira yochepetsera magazi m'thupi.

Chifukwa chake, mphamvu ya hemostatic ya thupi imatha kugawidwa m'magawo atatu. Gawo loyamba limapangidwa ndi kuyanjana pakati pa mitsempha yamagazi ndi ma platelet, komwe kumatchedwa primary hemostasis; gawo lachiwiri ndi kuyambitsa kwa coagulation factors, ndi kupangidwa kwa reticulated coagulation fibrin, yomwe imakulunga ma platelet ndikukhala strong thrombus, komwe kumatchedwa secondary hemostasis, komwe ndi komwe timatcha coagulation; komabe, magazi akasiya kutuluka, vuto lina limabuka m'thupi, ndiko kuti, mitsempha yamagazi imatsekedwa, zomwe zimakhudza magazi, kotero gawo lachitatu la hemostasis ndi. Mphamvu yosungunuka ya thrombus ndi yakuti pamene mitsempha yamagazi ikwaniritsa mphamvu ya hemostasis ndi kukonzanso, thrombus imasungunuka kuti ibwezeretse kuyenda bwino kwa mitsempha yamagazi.

Zikuoneka kuti kutsekeka kwa magazi kwenikweni ndi gawo la kutsekeka kwa magazi. Kutsekeka kwa magazi m'thupi ndi kovuta kwambiri. Kumatha kugwira ntchito pamene thupi likufunikira, ndipo kutsekeka kwa magazi kukafika pa cholinga chake, kumatha kusungunula magazi m'nthawi yoyenera ndikuchira. Mitsempha yamagazi imatsegulidwa kuti thupi ligwire ntchito bwino, chomwe ndi cholinga chofunikira cha kutsekeka kwa magazi.

Matenda ofala kwambiri otuluka magazi amagwera m'magulu awiri otsatirawa:

pa

1. Kusakhazikika kwa mitsempha yamagazi ndi ma platelet

Mwachitsanzo: vasculitis kapena ma platelet otsika, odwala nthawi zambiri amakhala ndi madontho ang'onoang'ono otuluka magazi m'miyendo ya m'munsi, omwe ndi purpura.

pa

2. Chinthu chosazolowereka chokhudza magazi

Kuphatikizapo matenda a hemophilia obadwa nawo ndi matenda a Wein-Weber kapena matenda a chiwindi omwe apezeka, poizoni wa makoswe, ndi zina zotero, nthawi zambiri pamakhala mawanga akuluakulu a ecchymosis m'thupi, kapena kutuluka magazi m'mitsempha.

Chifukwa chake, ngati muli ndi magazi osazolowereka omwe atchulidwa pamwambapa, muyenera kufunsa dokotala wa magazi mwachangu momwe mungathere.
